BACKGROUND Post-traumatic stress disorder (PTSD) is associated with atypical responses to emotional face stimuli with preferential processing given to threat-related facial expressions via hyperactive amygdalae disengaged from medial prefrontal modulation. METHOD We examined implicit emotional face perception in soldiers with (n = 20) and without (n = 25) PTSD using magnetoencephalography to ...

To design robots or embodied conversational agents that can accurately display facial expressions indicating an emotional state, we need technology to produce those facial expressions, and research that investigates the relationship between those technologies and human social perception of those artificial faces. Our starting point is assessing human perception of core facial information: Movin...

Abstract The topic of the human face is addressed from a biocultural perspective, focusing on empirical investigation how represented, perceived, and evaluated in artistic portraits self-portraits XVth to XVIIth century. To do so, crucial role played by social cognition introduced, starting development, showing that neonatal facial imitation face-to-face dyadic interactions provide grounding el...

This paper aims at generating a new face based on the human like description using a new concept. The FASY (FAce SYnthesis) System is a Face Database Retrieval and new Face generation System that is under development. One of its main features is the generation of the requested face when it is not found in the existing database, which allows a continuous growing of the database also.

Resource-sharing between spatial and temporal processing was investigated using dual task methodology to construct performance operating characteristics. Spatial tasks involved discrimination of line length and temporal tasks involved discrimination of duration. Preliminary results suggest that a tradeoff occurs within the easier task of the two difficulty levels, but that a simple tradeoff is ...

This study investigates F0, intensity and duration as acoustic parameters for the perception changing their relative weight, according to the perceptual development. Four groups – native Japanese who have studied German for one year at the Department of German, native Germans who don’t understand Japanese, Japanese students who had lived in Germany for more than one year, and German students wh...

How we understand the relationship between synesthetic and normal perception depends both on how we conceive of synesthetic perception and normal perception. In this paper I’ll argue that, given what we know about both, the most plausible view is that synesthesia is not a fundamentally distinct, pathological outlier relative to normal perception; rather, it is best understood as continuous with...

In this paper we study how children of different age groups (8 and 12 years old) and with different cultural backgrounds (Dutch and Pakistani) signal positive and negative emotions in audiovisual speech. Data was collected in an ethical way using a simple but surprisingly effective game in which pairs of participants have to guess whether an upcoming card will contain a higher or lower number t...

The recognition of faces is one of the easiest and the most frequently used by adult human method of distinction between known and unknown persons and identification of these familiar. Usually we benefit from it even without the awareness of this process and similarly another people can recognize our identity basing only on the quick observation. Often such recognition is done even without our ...

We model the class of problem faced by a video broadcast director, who must act as an active perception agent to select a view of interest to a human from a range of possibilities. Real-time learning of a broadcast direction policy is achieved by efficient online Bayesian learning of the model’s parameters based on intermittent user feedback. In contrast to existing machine direction systems, w...
